The Penis – Does Size or Shape Matter?

The penis is the male external genitalia that consist of nerves,
fibrous tissues, blood vessels, and three parallel chambers of spongy
tissues. The two larger chambers known as the corpora cavernosa lie
side by side above the smaller chamber called the corpus spongiosum.

Corpora cavernosa are rich in blood vessels and become engorge
with blood during sexual arousal causing penile erection. Corpus
spongiosum lie between the two larger chambers contains the urethra for
releasing urine and semen. Large numbers of muscles are present at the
base of penis which helps to eject semen and urine out of the body.

The flow of blood in and out of the corpora cavernosa is control by
arteries and veins. During sexual arousal, arteries that supply blood
into the corpora cavernosa open up to increase blood flow into the
chamber and the veins become constricted preventing blood flow out of
the chamber causing penile erection.

During flaccid state, arteries that supply blood into the corpora
cavernosa closes which reduces blood flow into the chamber and the
veins open up causing blood flow out of the chamber and penile become
flaccid.

The penis is a sex organ and a reproductive organ. The only
function is sexual arousal and passage for releasing urine and semen.
The external part of the penile excluding the head is called the shaft
and the smooth head is called the glans. The penile shaft is covered by
hairless loose skin known as foreskin that also covers the glans. In
some men the foreskin covered the entire glans and in others only
portion of the glans is covered.

In most men the foreskin can be retracted to expose the glans and in
some men the foreskin are removed at birth with surgical procedures
known as
circumcision. Male circumcision is mainly practiced as part of the cultural or
religious beliefs. Male circumcision may involve removing part of the
foreskin or the entire foreskin maybe completely removed.

The glans has large number of nerves ending and is highly
sensitive to touch. There are two specific locations on the glans that
are highly responsive to stimulation. One area is known as the corona
where the glans rises from the shaft and the other is known as the
frenulum which is a highly sensitive skin that connects the glans to the
shaft on the underside.

Most men enjoy stimulating the two areas of penis during
masturbation or sexual activity. Some may prefer stimulating the glans
with foreskin covering and others may prefer direct stimulation of the
glans.

Smegma can accumulate under the foreskin and collect around the
glans that may cause pain during sexual arousal. Smegma is the
combination of genital secretions, skin cells, and bacteria that
accumulate in moist areas of the glans of both male and female
genitalia. You can clean the smegma by retracting the foreskin and wash
the glans gently with soap and water on daily basis to prevent the
buildup of smegma.
